LONGEVITY
Risk: How important is longevity risk within life insurance and
pensions? How aware are pension funds about the risks within
their policies?
Thomas Streiff (TS): Pension funds and insurance companies are
well aware of the risks. What to do about the risk is the bigger
challenge. Managing longevity is extremely important and it is a
significant risk. If you just look at the annuity market place in the US
– which is where most of the annuity business is today – it is an
extremely large business and has been growing rapidly. In the first
half of this year, it experienced 10% growth over last year. The living
benefits in annuities are much more complicated than a typical
pension annuity, which is a straight life annuity or joint life annuity.
Christopher Murphy (CM): The actuarial profession has been
tasked with predicting mortality through the years, but history tells
us that it’s extremely difficult to get these assumptions right and
has highlighted the difficulty in dealing with this issue.
Risk: Are pension funds aware of some of the deficiencies of the
data on mortality?
Matthieu Robert (MR): We don’t have full transparency, but pension
funds have been slow to update their estimates of life expectancy. In
the UK, some companies have recently been forced to be more
conservative and increase the life expectancy of their policy holders
under IAS19 and the Pension Protection Act, however, there are still
some using aggressive assumptions. As for their awareness, we can
see from the end of the 1990s and the beginning of this decade that
it is only when long-dated interest rates dropped to historical low
levels that they realised they had problems with their guaranteed
annuity obligations and the potential losses they were facing. They
bought a lot of long-dated receiver swaptions to cover their risk. It is
interesting to see how quickly they went from no hedge to
executing huge hedging programmes against falling interest rates.
Nicolas Tabardel (NT): If we go back to before 2000, the typical
pension fund was heavily invested in equities, and equities were
going up so longevity was not too much of a concern to anyone.
After 2000, equities went down and rates fell, which increased
liabilities and people started to realise that there is a lot of risk here.
Since then, we have seen more and more liability-driven
investment (LDI) and, in a typical LDI approach, the manager of the
pension will try to quantify and hedge inflation risk, interest rate risk
and longevity risk. The first two are now quite easy to deal with, but
for longevity risk there are a lack of instruments, although there is
more and more will to deal with this.
Evan Guppy (EG): The reason we are seeing pension buyouts is that
people are really concerned about interest rate risk, inflation risk and
longevity risk. There is a premium they can pay in order to make those
Uncertainties about future mortality and life expectancy are proving a problem for pension
funds and insurance companies. They are increasingly looking to hedge longevity risk, but
the market is lacking instruments for it to hedge against. Last month, in conjunction with
Tullett Prebon, Risk hosted a roundtable to discuss the ways of assessing longevity risk and the
development of such a market

problems go away. The problem is that the cost of that risk transfer is
too great for many pension funds, which is why we need capital
markets solutions to bring in more participants to take on that risk.
Risk: Do you feel that the clients you are speaking with are
moving more towards the buyout solution or are people crying
out for more fi nancial derivatives to manage longevity?
Yan Phoa (YP): The emergence of the bulk buyout business was
driven by a big change in the regulatory and accounting regimes
for pension funds. The UK has probably gone furthest in valuing
and marking to market these liabilities through the corporate
balance sheet. Rating agencies have started to focus on them too.
For the pension fund trustees, there is much more personal liability
to ensure they are acting in the best interests of the pensioners. So,
overall, people are much more aware of risk. Pension trustees are
looking much more at whether they are adequately funded from a
personal liability perspective. What this has done is make
corporates realise that they don’t want to have this unknown
liability hanging over them. This, in turn, has driven the emergence
of this buyout market where people are willing to take on that risk
at a premium to where, historically, those liabilities had been
valued. Insurance companies have to price it for the uncertainty of
the future. From the pension funds’ perspective, as long as the
corporate sponsor is fi nancially sound, any mistakes in the
estimation of this risk can be rectifi ed by going back and changing
the contribution they are receiving. A pension fund will mark it
only to where it is reasonable, whereas an insurance company has
to mark it for future uncertainty and that naturally is done at a cost
as they will have to be more defensive in their estimates.
Risk: There has been a call from the media for pension funds to be
more transparent in their mortality assumptions. Is this possible?
Barbara Blasel (BB): It is possible, although the modelling and the
determining of the data is an issue. All the evidence points to a
systemic underestimate of future longevity improvement at all times
in the past. We somehow have to get there to determine longevity
and improvement in mortality in order to build up a market, but it
will take some time to fi nd standardised mechanisms to do so.
CM: If there is a deep and liquid market in longevity risk, this problem
would go away. We would no longer need to make the assumptions.
If you go back 10 years, pension funds needed to make infl ation
assumptions, now they don’t. The market decides it for them.
Risk: What role have reinsurers played so far? Is that the best
route to take?
TS: We are going to see an increasing role for reinsurers. We now
see reinsurers emerging as a potential solution for all of these risks
and taking them in a package. Most investment banks look at the
risk of infl ation and capital markets as part of the things that they
do, but they don’t necessarily want to deal with longevity risk or
behaviour risk that we are talking about in annuity, so they want
that to go somewhere else, whereas reinsurers could take on all of
the risk and then distribute what they don’t want.
Benoit Chriqui (BC): The advantage of reinsurers is that they can
be fl exible in terms of structures or formats, they can be quite
accommodative. But they are not going to be the driver of the
market. First, they are interested in risk diversifi cation, and longevity
risk is just one type of risk, even when you consider very diff erent
pension schemes, so they will be limited in terms of size of
transaction they are willing to do. Second, they are relative-value
players, so they are only going to be interested in the trade if they
can collect a premium to where they see fair value. The pensions
on the other hand might only be interested in hedging if it is close
to where they are currently valuing their liabilities, so might be
reluctant to trade at the premium demanded by reinsurers.
BB: Reinsurers have some kind of diversifi cation by not only
absorbing longevity risk but also mortality risk. It’s not a perfect hedge
but there is some degree of diversifi cation that probably allows them
to absorb more risk on the longevity side. But there is one constraint
on the reinsurance side, which is capacity. In recent years, there has
been a decrease in the number of reinsurance players.
Michaël Picot (MP): Giving all the risk to a handful of companies is
not the targeted solution. Reinsurers might have the capacity to
generate more returns than the pension funds, but they would
need to extract the longevity component and distribute it to the
market. This is precisely a role longevity derivatives can play.
Risk: There have been attempts to launch longevity securities;
BNP Paribas was involved in one of the bonds in late 2004. How
do you describe the attempts to get this off the ground so far?
BB: The feedback was very positive. That was the fi rst attempt to
hedge against longevity trends. It was probably a bit too early for the
market, therefore ultimately the bond hasn’t been issued. The reasons
for that are manifold. One was the introduction of the pension reform
at the same time, so pension funds were more focused on that. Also, a
supranational was the issuer, so yield was lower than some participants
were expecting. On the other hand, to provide a stable, long-dated
asset, it was important to have a high rating from the issuer.
Risk: What is the potential for longevity-linked securities?
NT: One issue with the bond format is that the buyer then takes on
the credit risk of the issuer. If you’re trying to hedge longevity risk
with a () bond, you introduce a new problem with the credit risk,
and that is at least as important as the longevity risk you were
concerned with in the fi rst place. Maybe a derivative format is better,
because the credit risk can be managed with a collateral agreement.
CM: That was the problem with the BNP Paribas structure in that it
wasn’t leveraged in any way. So, if you wanted to hedge out your
longevity risk, you would have to put 100% of your assets in this
bond. That is just not a feasibly solution. At Morgan Stanley, we
took a mandate from an insurer and worked on a similar type of
project for 12 months where we designed a bond that would pay a

high coupon that would be reduced if longevity turned out to be
greater than current assumptions. The problem was that at least
half of the investors were not interested and 80% of the remaining
half was not allowed to invest in this product.
YP: Having a funded instrument is not going to be how the market
moves forward. The other problem with the bond is that, for it to
have some sort of liquidity, it needs to be large and a one-size-fits-
all solution. It is going to be hard to get enough people to feel
comfortable that the basis risk is acceptable.
NT: There is also the issue of supply. We know where the demand
will come from: pension funds. But who is going to supply the risk
that we need? There is a partial hedge in mortality risk, but there is
still a need in the tail of the distribution that we cannot source.
Risk: What are your views on the basis risk issue and the one-
size-fits-all argument?
TS: I’m optimistic about a future for an index approach but my
optimism is tempered by the issues raised. If I separate the market
into annuity and pension funds, the basis risk is probably more
manageable on the pension side. It’s still an issue but a bit more
manageable. On the annuity market, because those are voluntary
buyers and you have natural anti-selection with voluntary buyers,
the basis risk can be much bigger.
CM: Doesn’t that suggest that you just need another index?
TS: It may, in fact. If you can match an index that takes into account
your anti-selection then you’re in business. That is difficult to do
because what you’re trying is to get the buyer to be the seller and
that is where your challenge is.
YP: On the annuity side, it’s a much more concentrated market and
the competitive advantage of annuity providers is the information
they have. That data is proprietary and for them to say they are
going to contribute in-house data that is their competitive
advantage into an industry effort is going to be tough.
TS: You can get them to contribute the data such that they are
giving you meaningful information by virtue of what they are
buying and selling as opposed to what they collect in their own
database. That is hard to achieve but that is how you will end up
with an index that is matching what is actually happening in a
place where you have voluntary buyers.
EG: It is going to be quite difficult for a funded instrument to work
because the trustees and pension firms that are most aggressive in
trying to address their problems are the guys that are pursuing
interest rate and inflation strategies. For them to change their
approach to longevity and to reintegrate their asset and liability
management seems unlikely. But, if you’re trying to go down the
derivatives route, then sure, there is no reason why it couldn’t work.
MR: Concerning the index, if you want an interdealer derivatives
market on longevity risk to develop, you have to agree on one or
two indexes. It is most likely that we will have global indexes (i.e.,
on national population) trading. Pension funds will have the choice
to hedge their exposure with the global index and keep the basis
risk or to try to pass the risk relative to the subindex to which they
are exposed to a bank. With the first approach, I think it is possible
to work with the pension fund on historical analysis and
comparison between the global population and the particular
population of the subindex in order to come up with some
appropriate hedge ratio between the pension fund risk on the
subindex and the hedge on the global index.
Risk: There have been a number of attempts by banks that have
started developing indexes. Is there an obvious candidate as to
the type of index we could use? What are the obstacles?
BB: The idea should be to work on some kind of standardised index
because it’s the only way to allow for the development of a
derivatives market and to have transparent indexes that are tradable.
On the other hand, even setting up these indexes is already an issue
because forecasting longevity expectations for the next 30 years is
quite hard. We have to start with population mortality data because
this database has sufficient historical information. To set up forecasts
for the next 25–30 years, one would need an observation period of
30 years or even more. It would be great to have also subindexes
that cover certain groups of the population, such as specific
professional groups, and also cover regional differences within one
country. But, in the end, it comes down to availability of robust data.
Although longevity is seen as a global risk, risk sellers would
definitely want to have their particular geographic exposure
reflected, so one could possibly think of a handful of indexes for the
main markets from which companies can choose and design their
individual derivatives to reflect their specific exposure. This would, in
turn, become their individual exposure.
MP: Even population mortality rate is a debatable issue because it
is a difficult figure to produce, for example, due to infrequent
population censuses. Still, I expect to see two types of indexes. The
first one would be life expectancy index, just quoting life
expectancy at birth. The second approach is the life metrics
approach based on explicit qx ratio, which is much more ambitious
and therefore allows things like quoting the different life
expectancies at a given age. It also gives more room to hedge
longevity with mortality and a simple way to address the basis risk
with a ‘technical age’ approach (sliding on the curve to project one’s
specific population on the general population).
BC: On the derivative side, I agree it is impossible to have the market
develop with multiple indexes. There is not enough two-sided
interest to create many small markets, so you need to have everyone
focus on one specific index to help improve liquidity. The problem
on the pension side is that they will not view a central index as a
particularily good metric for their own longevity exposure. There
needs to be education to the pensions in terms of showing and
explaining the correlation between different indexes and how using

SPONSORED ROUNDTABLESPONSORED ROUNDTABLE
a central index would not be a bad hedge. But even then, it will still
be diffi cult, because although a central index would be a good
hedge, if it is used to value the liabilities, it could still give a very
diff erent value because of basis diff erence, and pensions might have
a hard time not valuing their liabilities at the same level as their
hedge. The other point is that there are lots of banks thinking about
indexes and how to construct them, but the fi rst diffi culty is data
collection. You also need to have a robust metric and have a
transparent way of collection that is unbiased. On that note, it would
help if the government got involved and stepped in to recommend
a metric to be used in valuing longevity liabilities, and then have an
offi ce that would be in charge of collecting the data.
YP: We need a transparent and impartial data collection method.
The government fi ts that role very well. You got to have the
commitment to produce the data on an ongoing basis. We’re
talking about transactions that are going to span the next 20–40
years. The market needs to feel comfortable that the data is going
to be provided in a consistent manner. It needs to be timely, you
need a long historical series so you can understand the behaviour
of the index in the past. There will be basis risk between how their
particular population behaves versus the general population, but
what you’re trying to hedge is the change in the trend in the future.
EG: I don’t think the government needs to get involved. There are
examples in the property market and indeed in credit derivatives
where it is quite possible to have an independent market-wide body
to collect the data. The key point is really more about independence.
If you want to use derivatives to draw more players into the market,
that means you want data that is supplied by someone who is visibly
independent, visibly reliable. If you’re saying you want life insurers and
pension funds to be trading with money managers and hedge funds
based on data that is collected by the insurers and the pension funds,
then it’s probably not going to be very appealing for the money
managers. The government is already collecting that for the widest
possible population set you can have in the UK. The other point is
how do you use that to construct a tradable index? I think people
would be more comfortable if, as a group, we come up with some
methodology and some index that would either be an independent
market-based index that could evolve out of something that was one
fi rm’s idea but is ultimately owned by the whole market.
NT: I see a parallel to the infl ation market. There is a basic trade-off
between liquidity and basis risk in trading one single index versus
multiple indexes. In the infl ation market in Europe, the market is
concentrated on European infl ation – that’s where the liquidity is. It’s
transparent and liquid. On the other hand, you have fi rms’ liabilities
that are not indexed to European infl ation but that use European
infl ation to hedge. They can use French infl ation, or Italian or Spanish
but it’s less liquid and is more expensive. It is less transparent. We are
always going to have this kind of trade-off . Whether we trade a single
longevity index or several, the question is: who is going to
warehouse the basis risk? Is it better to warehouse the basis risk in
banks or in the pension funds or clients? If the bank is required to
provide customised index for clients, then it will have to hedge with
a liquid index and warehouse the basis risk. If it has a cost, is it more
effi cient to have a cost in the bank or to have the cost at the client?
MR: There is no choice at the beginning but to go for a
standardised index. What is important is the transparency and the
independence in the building process of the index. I am quite
sceptical of any index that is built by a bank, even if it is relatively
transparent. I would typically prefer something built by a
government institute. For example, the Offi ce of National Statistics
(ONS) in the UK has already started collecting data on mortality
rates for the country. The ONS data is published on a annual basis.
The idea will be to use this set of data and have a panel of banks
agreeing on how to construct the index based on this set of data.
TS: Standardisation is a good idea. A certifi ed pension actuary
society and a society of actuaries on the insurance side could play a
role in gathering the data. They do a better job of gathering and
analysing the relevant data. In stable population countries, generally
mortality data is better than in countries where you have a lot of
turnover in the population through emigration or immigration.
General population data in the US is skewed because of the high
level of immigration. That is an example where we would never rely
on that data. We would rely on Society of Actuaries data or pension
actuary data if it’s on the pension side. That’s where we have
historically looked for standardised data. That is exactly what you are
doing in buyout situations: you are placing the longevity risk with an
entity that understands the data from a very diff erent perspective
than what you get in a generalised government index. I’m in favour
of a standardised index, but it’s not as big an answer as might
otherwise be viewed because of specifi c challenges of the data.
Nadir Latif: There has been a lot of discussion about indexes based
on government statistics. Would the market prefer an index
provider that is owned by several of the large banks and/or the
interdealer brokers? In terms of developing the market place,
getting a group of banks to agree to take joint ownership of a
company that is independent in constructing the methodology of
the index might be the quicker way to develop the market rather
than going down the route of a link with a government-based
entity. Of course the independent company could still base the
index on government-based data.
BC: If I were a pension fund, I would disagree with a group of banks
gathering the data to value my liabilities. If diff erent banks in the
group had diff erent interests, then this method would be fi ne, but
here banks are likely to always take the other side of the pensions.
The most important thing in this case is to get the pension funds
comfortable with the level of impartiality and that means not
owning the collection process or the creation of the index process.
EG: One of the advantages of having an independent fi rm collect
Evan Guppy
Yan Phoa
1107_Risk_longevity.indd 47 30/10/07 11:18:21
the data is that, as soon as the firm is up and running and
publishing the index, you then have the banks that have
committed themselves to supporting the index.
YP: One concern is continuity of such an index. It has to be a long-
term commitment. You have to have the commitment to see the
market succeed, at the same time, you have to make the
commitment to fund the index.
NT: As a client, I would be very wary of an index that is sponsored
directly by banks, whether by a single bank or a group of banks.
What happens if my bank doesn’t sponsor the index? Do I get the
data later, do other people have better information? That’s the
dangerous issue. There is also an issue of the continuity of such an
index. It’s hard to guarantee that as a private entity that is owned
by a group of banks. The only entity that can guarantee that over a
lengthy time horizon is the government.
CM: It needs to be based on government data, but there is no way
that the government is going to start publishing an index, so it will
have to be an independent index provider but maybe based on ONS
data. The involvement of actuaries in publishing that index would be
detrimental to the success of that index and there is widespread
scepticism about the value-added of actuaries in that process.
BC: The end-user should ultimately decide. There should be more
fact-gathering as to what type of central index would make sense
to somebody who has exposure to a subindex. Because the basis
risk is so important, there is a high likelihood that, if banks get
together and set up an index without properly consulting the end-
user, that this index will not be well received.
Risk: Is there any interest from clients about having a solution
built for them? Is there consensus over the methodology for a
standardised index?
BB: Clients are relatively open in terms of the types of solutions
they are looking for. In terms of indexes, market players need to get
comfortable with the modelling, and then transparency and
continuation are key in this context. As long as one can agree on a
single methodology and really continuously focus on this
methodology, then this is the driver for market participants getting
comfortable with the modelling and the analysis.
CM: Having a level of subjectivity in the creation of the index is
probably something that the pension and life insurance companies
would want to see because that is what they are comfortable with
and used to. But if you are talking about attracting new pools of
capital, like hedge funds, to this market, we will have extreme
scepticism about any potential tweaking to the underlying data
that is at all subjective.
YP: I think that is a fair point. There’s trying to get the best
information out of the data and trying to keep the data as close to
the raw form as possible. I would argue for trading that each
institution can do what it wants with the data in-house. What you
actually trade and settle the trades against, you may find that you
always want to revert to the raw data.
TS: And that’s how mortality tables are used now in the insurance
industry. They take a standard mortality table and adjust it for their
circumstances. So they will take what is, in essence, raw data and
put their own subjectivity on it based on how they want to price
that business. So I can see exactly the same thing happening here.
CM: To some extent, banks are indifferent as to how the index is
constructed. It matters more to the end-users who are going to
end up wearing the risk. And so, maybe the pension and insurance
industry should be discussing this topic as well and saying what
they want the index to look like.
Risk: How big do you actually see this market becoming? Are we
seeing any swaps and forwards transacted at this point in time,
or is it a little too early?
BC: There is some activity. But there are a couple of issues on which
we have touched that make it a little difficult to see how this market
is going to develop into something very large such as the inflation
market. There is significant end-user interest, and defined benefits
schemes are heavily exposed to longevity. But you have a very one-
sided business. One problem I see with this market developing is
that the end-users are currently using their own assumptions. If they
used the buyout assumptions, it would be more expensive for them.
If a market started to develop, where would that market start to
establish itself ? At the buyout assumption? Even more expensive
than the buyout level? And then, once you have an actual active
market, these pension funds to some extent will have to market-to-
market. Even if they claim their basis is different, it will become more
difficult to justify the assumptions they are using. To some extent,
the end-users who most need this market to hedge their liabilities
might also be reluctant to see it develop in a transparent way.
EG: There is a definite first-mover advantage for the pension
schemes that do something if a market gets up and running. Part of
the reason for going down a capital markets and derivatives route is
trying to get more players involved. The question is whether there
are sufficient investors interested in taking on some of that risk to
offset the £1 trillion in pension liabilities. That is the great unknown
at the moment and, until the market gets up and running, it is
difficult to see whether money managers, hedge funds or anybody
else are actually going to be willing and how much money they are
going to be willing to put up and at what price. One thing I would
hope is that, if you are going to have more people involved in that
space that can take on the mortality risk, then hopefully the market
will start to offer inside where buyouts are at the moment.
CM: This market may take a lot longer to develop than perhaps
we’re all hoping for because you can argue now that pension funds
potentially shouldn’t be marking to an FRS-17 mark, they should be
marking to buyout. Buyout prices include the longevity risk
associated – that is the only thing that’s left to hedge out. I don’t see

SPONSORED ROUNDTABLE
any appetite at all for doing that. Clearly, legislation has gone a long
way to getting pension funds to address the risk embedded in their
liabilities and mark them to market, but the industry has been
kicked so much that there is no great appetite to create more stress
in the system. I’m sceptical as to how this market will develop. I’m
not so optimistic that it will come inside the buyout price. For this
market to take off, you need new pools of capital to come in and, if
money is made available to take on some of this risk, you would be
much more inclined to do it within a buyout vehicle because you
not only get to take longevity risk at perhaps a good price but you
also get control of assets that you can work over time.
Risk: Have you seen any trades of this kind in the market?
NT: Not directly in longevity derivatives, but the buyout market
has been very active. There has been a recent twist in the buyout
market, where Citi did a transaction with Thomson Regional
Newspaper (TRN). TRN effectively transferred the financial
responsibility for its pension fund to Citi. What is interesting is that
it allowed us to operate under pension fund regulations, not
insurance regulations, which may be more attractive in certain
circumstances. That is where a longevity market is needed. It’s not
as simple as hedging interest rate risk. It’s a trend that has started
and will continue to develop. We will see more and more transfers
because it’s a very efficient way to do this. It is natural for banks to
use an LDI approach after transfers. This is going to create a lot of
demand for longevity derivatives.
Risk: Are more institutions moving towards this structure? Were
there any regulatory hurdles that had to be crossed
NT: We are seeing more and more enquiries about this specific
transfer. A lot of people are interested in doing similar deals. In
terms of regulatory hurdles, there were a few things to check in
order to ensure that we could actually do this, as well as making
sure that members and trustees were kept in the loop.
Risk: Do we need to come up with more capital-efficient
structures before the market can gain traction?
TS: One of the ways I look at it is dividing up the markets and then
dividing up the risks within those markets. If you look at the US
pensions, there is the US defined-benefit pension market, which is
worth $2.3 trillion. Meanwhile, US variable annuities – most of which
have benefits that are hedgeable in this way – are worth $1.3 trillion.
It is a huge market place. The part of the market that has the most
capital markets solutions attached to it so far is the US variable
annuity market. There are banks that are stepping in and taking
longevity risk in those transactions, there are reinsurers that are
stepping in, there are those that are just taking the volatility aspects
of it. The insurance companies keep the longevity risk if they want to,
and there are plenty that don’t want to. But they don’t want the
volatility and the mark-to-market aspect of the liability, so they’ll ask
an investment bank to come in and take out that volatility. I may be
the most optimistic person at the table in seeing this market develop
and maybe that is because I see it developing so rapidly and so
much money being spent by insurers in the US to hedge these risks
today in a lot of different ways. They range from futures to cashflow-
structured over-the-counter hedges and everything in between.
YP: The trend is for risk to be transferred now that people are much
more aware of risk and the impact of volatility. That is going to be a
secular long-term trend – risk is going to be aggregated and
managed and it will be from different sources and disaggregated
into its different components or different risk aspects, some of
which can be hedged today and some of which will need to find a
market. It is a question of what price and how much capital you
can attract to take on that risk. That is something that everyone is
bullish about. What form that takes with regard to mortality and
longevity risk is hard to say at this point but it will happen, that risk
will get disaggregated from all the other risks that traditionally
come bundled together.
Risk: Is this going to be vanilla in terms of derivatives?
MP: I do not think that longevity derivatives will be merely designed
to address the pure longevity risk. They will also be tailored to meet
the demands of the new regulatory or accounting rules and their
underlying shift towards mark-to-market approaches. These typically
require giving a value to the mortality/longevity contingencies
embedded in products otherwise sensitive to market shifts.
EG: As with inflation it is an unbalanced market as end-users
ultimately get what they want. Banks end up with basis risk
between different inflation indexes or seasonality risk that they
cannot hedge but hope that they have priced correctly and will
balance out. It is hard to see mortality as being similar to that. The
market will need to find people who are willing to take on and
price basis risk in return for a risk premium and it is there that the
transfer of risk from end-users will take place.
BC: Swaps are the building blocks. The derivatisation of the risk
really happens when you have different interests and an active
market. The problem with the longevity market is that it is very
much a buy-and-hold market, so I don’t see volumes being very
large in terms of interbank dealing and, if they’re not very large, then
it is very difficult to go to the next level of derivatisation. It is going
to be difficult to have an interbank market on volatility, for example,
for a long time. That being said, because transactions are likely to be
bespoke, end-user structures could very well immediately be very
complex. Maybe one could have some optionality or something
exotic embedded in the first trade with a reinsurer on one side, a
pension on the other side and a bank providing the structuring and
keeping the unhedgeable correlation or volatility risk. But, in terms
of the development of the interbank market, it should be slow.
NT: The first step is to agree on a forward curve and we are not even
there yet. If there is going to be any complexity in the market, there is
more going to be because of different subindexes that people want
to trade rather than trading more complex structures that include
volatility features. The subindexes will be the drivers of the complexity.
